“…Basically there are three mechanical principles that will work on the Pontoon, namely Inertia, Gravity and Viscous Effect [9]. The dynamic response of floating solar power plants can be determined using analytical methods, then the results are validated using Computational Fluid Dynamics (CFD) with the focus of important parameters being wave height, wave period, water depth and pontoon diameter [10].…”

“…Response Amplitude Operator (RAO) is a value used to determine the response of barges when operating in a particular water body to six degrees of freedom (6 DOF) [10]. It is ensure safe and energy efficient in marine operations which is waves are often modeled in terms of an idealized wave spectrum, and the RAOs are usually obtained through model tests or numerical software.…”

Floating Photovoltaics (FPV) are renewable energy producing technological breaktroughs whic are suitable to circumtances of lakes across Indonesia. The core of this technology is the function of working transformers installed on the pontoons. An FPV with 145 Mwac capacity is designed to run on Cirata weir by utilizing pontoons with the length of 16.5 meters. The hydrodynamic response in the form of plane and rotation movements due to surrounding loads (including but not limited to wave, wind and sea depth data) calculated by using Response Amplitude Operator (RAO) concept. The wave period measured in meter from 0 to 180 ° incoming degree, the biggest translational response comes from pontoon i.e 0.986 (m/m) in sway direction, spread mooring is used to limit the pontoon’s movement. Using weighing concept, in operating condition Tension Mooring Line is obtained at the value of 1.67 for pontoon. While in extreme condition the obtained value is 2.5.

“…While RES are abundantly available offshore, significant engineering challenges arise pertaining to the deployment, operation and maintenance of RE devices at sea. A case in point is floating offshore photovoltaics [9,10] that are constrained to having a large water plane area to maximize their energy conversion efficiency at the expense of a high exposure to wave loads. Furthermore, sea faring vessels undertaking maintenance works offshore, for example, at offshore wind farms, may be constrained to return to the base under very rough weather conditions.…”

Floating breakwaters have recently been generating increasing interest as a vital means to provide shelter and protect the ever-increasing number of structures deployed at sea. Notwithstanding the novel ideas being put forward, to date, floating breakwater deployment has been limited to inshore and shallow water areas. The scale of such structures has been restricted to the smaller spectrum. Furthermore, whilst some concepts to integrate floating breakwaters with other offshore systems have been proposed to benefit from cost-sharing strategies, studies related to floating breakwaters integrating energy storage are lacking in the open literature. The present research investigates the wave attenuating and dynamic performance of a large-scale floating breakwater in deep seas with a hydro-pneumatic energy storage system also integrated within the structure. This article highlights the arising need for floating breakwaters and sheds light on the present-day technological status of floating wave breakers. It then lays the ground for the proposed, novel floating breakwater concept that aims to address the current knowledge gaps in this field of study. The simulation results generated from numerical modelling via the potential flow solver ANSYS® AQWA™ have been promising, connoting that the addition of hydro-pneumatic energy storage to a floating breakwater will not lead to a degradation in the dynamic performance or wave breaking efficiency of the floating structure.

“…Song et al [19] compared the effects of a fixed connection and a hinged connection on the dynamic response of the FPV array under wave conditions, and the results indicated that the fixed connection can effectively reduce the mooring forces. Al-Yacouby et al [20] and Friel et al [21] carried out parametric studies on the dynamic response of the single horizontal cylindrical floating platform under the action of regular and irregular waves, including the immersion depth, diameter of the pontoon, wave height, and wave period. Gharechae et al [22] proposed a semi-analytical method for solving the vertical acceleration of an elastic circular floating system, and the research indicated that, as the wave number increases, the hydroelastic interactions between the floating structures become increasingly significant.…”

“…In summary, the existing research focuses mostly on the hydrodynamic characteristics of an FPV array under one single load; however, in engineering, wind, waves, and currents often exist simultaneously. In addition, the study should be based on the entire FPV array rather than a single PV panel [20,21]. At present, there is a lack of research in this field.…”

The floating photovoltaic (FPV) array, which consists of tens or hundreds of rows of floating photovoltaic systems, exhibits great economic and environmental benefits. An FPV array arranged in the ocean will be subjected to the combined action of wind, waves, and currents during the installation, service, and maintenance processes; however, systematic research in this field is still lacking. As a representative of the FPV array, this study on the hydrodynamic characteristics of a single-row FPV system is a fundamental prerequisite for the safe design of large-scale FPV arrays in the near future. In this paper, based on the potential theory, a numerical model of a single-row FPV system with ten floating platforms is established with ANSYS-AQWA software. Following this, the hydrodynamic coefficients of a single floating platform are calculated and evaluated. After that, the dynamic responses of the FPV system under different load combinations are explored. Finally, the influence mechanism of wave parameters on the hydrodynamic characteristics of the FPV system is discussed in detail, including the wavelength and wave height. The results indicate that, within the scope of this study, the floating platforms have good seakeeping and stability. The wave load dominates for all conditions, and the presence of the current will affect the parameters of the wave. In addition, the relative relationship between the wavelength and the length of FPV system will affect their resonance effect, and the increase in wave height will significantly enhance the dynamic response of the FPV system. This study can help to provide references for the safety design of FPV arrays.
